Abstract

Background: Ureteral stenting after uncomplicated URSL (ureteroscopic lithotripsy) is preferred by most urologists. Routine stenting exposes patients to more stent related complications. This study was done to compare post-op outcomes of stented and non-stented URSLs and to determine the optimal stent duration time following uncomplicated URSLs at our institute.

Methods: A total 90 patients with ureteric stones of <1.4 cm size admitted to our Institute between August-2023 and March-2024 were treated by URSL and randomized to 3 groups namely-non-stented group (n=30); stented for 7 days group (n=30); stented for 14 days group (n=30). The patients were followed up for 4 weeks following URSL. The primary outcomes assessed were post-op LUTS, dysuria, flank/suprapubic pain, hematuria and stone free state. The secondary outcome assessed was rehospitalization rate.

Results: The incidence of flank pain, LUTS and dysuria was higher in the stented groups compared with non-stented group. Loin/suprapubic pain, Irritative symptoms were higher in the 14 days stented group than 7 days stented group. However, there was no statistical difference in the three groups in terms of stone-free rate. Mean operation time was less in non-stented group than in stented groups (p<0.05).

Conclusions: The non-stented group has less incidence of pain and irritative symptoms with comparative stone free rate to the stented groups. The incidence of post op stent related complications increases with increasing duration of stent. We suggest that it is not necessary to place a ureteral stent routinely after uncomplicated URSL for ureteric stones smaller than 1.4 cm.
